Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed February 7, 1905. Serial No. 2%.561.

To all whom, it may concern:

Be it known that I, MARTIN O. W ALLUM, a citizen of the United States,residing at Binford, in the county of Griggs, State of North Dakota,have invented certain new and useful improvements in Floor-Jacks; and ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to floor-jacks such as are employed for forcingfloor-boards into close contact with the next board, although it will ofcourse be understood that the tool may be used upon siding or whereverelse it may be applicable.

The object of the invention is to provide a tool of extreme simplicity,which as an article of manufacture will comprise but few parts and whichwill be simple and positive in its operation.

in the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in both the views,Figure 1 is a side elevation showing the tool in use. Fig. 2 is anelevation looking at right angles to Fig. 1.

Referring now to the drawings, there is shown a floor-jack comprising apresser block or head 5, the face of which is ribbed, as shown at 6, atone side of the head, while from the opposite face there projectsupwardly at an acute angle an arm 7, the free end of which is bifurcatedto form laterally-spaced ears 8.

.lfletween the cal-s8 is pivoted a hand-lever 9,

one end of which is pivoted between the cars 10, that project upwardlyfrom an anchor plate 11. From the under face of the plate 11 projecthook-fingers 12, the free ends of which are turned in a direction awayfrom the head 5, these lingers at one end of the plate projecting beyondsaid plate, as illustrated.

In the use of this tool the anchor-plate 11 is disposed upon a joist iffloor is being laid, and the head 5 is disposed against the board thatis to be forced into position for nailing. The lever 9 is then movedwith its upper end. in the direction of the head 5, with the result thatthe head is moved against the floor-board and forces the latter intoplace.

That is claimed is---- A tool of the class described comprising aheadhaving a corrugated face at one side and having an integral armprojecting from its opposite side at an acute angle thereto and havingspaced cars at its free end, a lever pivoted between the ears of saidarm, and an anchor-plate having hook-fingers projecting from its lowerface and beyond one end thereof in a direction opposite to the head,said anchor-plate having spaced ears projecting from its face oppositeto the fingers, and between which ears the lever is pivoted.

In testimony whereof I affix my signature in presence of two witnesses.
